S. Follin et al., INFLUENCE OF MICROPOROUS CHARACTERISTICS OF ACTIVATED CARBONS OIL THEPERFORMANCE OF AN ADSORPTION CYCLE FOR REFRIGERATION, Industrial & engineering chemistry research, 35(8), 1996, pp. 2632-2639
The performance of an adsorption refrigerating process, quantified by
the coefficient of refrigerating performance (COP), depends on the ads
orbent. From the Dubinin-Astakhov equation, it is possible to calculat
e the performance of a basic adsorption cycle, taking the characterist
ics of the adsorbate and the adsorbent into account. The influence of
the physical characteristics of the adsorbent on performance is shown
by way of the parameters of the Dubinin-Astakhov equation: total micro
pore volume, W-0, characteristic energy, E(o); and exponent, n. The in
fluence of the pore size dispersion is estimated thanks to the Dubinin
-Stoeckli equation and by comparison of the performances simulated wit
h measured characteristics of several activated carbons. This study sh
ows that there exists, for given thermodynamic conditions, an activate
d carbon having optimal physical characteristics that allows us to obt
ain the best performance.
